cally at but a sin 1e point for obviously refiietween the saddle and ducin friction spind e. Furthermore the spindle isso .con-

structed as to have a further point of 'contact with the spindle normally out of engagement with the spindle during high speeds therepf; This additional point of contact is for the purpose of preventing the swinging of the saddle upon the spindle prior to the time thatsaid spindle reaches a high degree of rotation.

The invention further aims to provide a saddle wherein the spindle contacting member is of such formation as to engage with in a curcumferential channel in the spindle for positivel preventing any longitudinal the saddle u after it has been properly isposed thereon.

A still'further object resides in the rovision of a saddle that is so cbnstructe as to permit the operator of the machineto readily grasp the unit spindle for the purpose of 'stoppingthe samewhich is neces sary in the rethreading of the'unit. A final salient object is to provide a bobbin supportin saddle for spinning and twisting units w erein means is provided for frictionally engaging the thread delivery bobbin for checking the rotation of the same during the operation of the unit. Other objects will become apparent as the nature of the invention is better understood, the same comprising the novel form, com

bination, and arrangement of parts-hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing wherein like reference characters indicate corresponding parts throughout theseveral views i Figure 1 is a fragmentary side-elevation of a spinning and twisting unitof the eneral construction shown and described in To this end there is'pron the spindle w my previously mentioned patent, the same being disclosed as equipped with a bobbin \supportingsaddle constructed in accordance with the present invention'and upon which is d sposed a thread delivery bobbin.-

Figure 2 is a section through the saddle upon the spindle, the full lines disclosing the normal position-of the saddle u n the spindle 'when a thread delivery b0 bin is associated therewith, while the dotted lines disclose the position of the saddle with respect to the spindle during the application or removal of the saddle.

Figure 3 is a top upon the spindle. Figure 4.is a vertical section taken substantially upon the line 4-4 of Figure 1.

Figure 5 is an enlar ed detail vertical sec:. tion taken substantially upon the line 5-5 of the same Figure for more clearly disclosing the single point of suspension of the saddle upon the spindle.

Figure 6 is a transverse section takensubstantially upon the line 66 of Figure 4 disclosing the second point of suspension between the saddle and spindle, which second plan view of the saddle j point of suspension is as previously stated normally out of contact with the spindle but that will engage the spindle during low speeds thereof to limit the wobbling ofthe saddle upon the spindle at such low speeds.

Figures 7 and 8 are perspectives of fiber .plat'es carried by the two points of suspension of the saddle, and

Figure 9 is a view mainly in front elevation of a modified form of saddle constructed for the purpose of permitting the suspension of two delivery bobbins upon the spindle, the bobbin receiving pins being disc osed in cross section. Y

The present saddle construction is of sheet metal formation consisting of'a single strip of'metal so bent as to provide a horizontal top wall 5, and an elongated depending rear wall 6, the inner portion of which is at direct right angles to the top wall, while the remainder thereof is bent diagonally forwardly as clearly indicated in Figures 1 and 2.

The forward end of the top wall 5 of the saddle is bent directly downwardly as at 7, and upon the rear face thereof is dis a fibre plate 8; The ends of the portion 7 "of the saddle are bent inwardly as at 9'-9' ill as to firmly secure the siime said The lower edge of this fiber plate extends below the edge of the saddle portion 7, and

' is formed at said lower edge with a relatively U-shaped notch 9, the edge of which is rounded as disclosed in Figure 2.

f This notch ofsaid fibre plate is for the :the saddle has been properly disposed thereon.

Upon the inner face of the saddle back wall 6 directly beneath the top wall 5 is a fibre plate 10 formed centrally with a cir cular opening 11 rounded at its edge and bein of adiameter greater than that of the spin e A which spindle en ages through said opening when the saddle is disposed thereon. The right angular portion of the saddle back wall 6 is formed at its opposite edges with struck out tongues 6-6', Figures-l, 4 and 6 that are to be bent overthe vertical edges of said fibre plate 10 to secure the same upon said right angular portion of the back wall, see Figure 4.

Secured to the diagonally extending por tion of the back wall of the saddle ad acent the lgwer end Itlhereof is a ligilr'ivyardly extending irect rig t angular in suppo in, 12 upon which is to be disposed a-th re zd elivery bobbin B. The angularity of the ma'or portion of the saddle back wall is suc that when thebobbin on the in 12 and the saddle hung upon the spin Ie, the center of gravity will be directly through the center ofthe fibre plate .8 so that this plate will have the greatest contact with the" spindle. 1 However, insomuch as the saddle will havea tendencyto wobble upon the spindle until the same reaches a 7 fibre plate 10 will engage said spindle and oonsequentl limit the'wobbling movement of thesadfie; It has however been estab lished by actual raictice of the invention that after the spindle reaches a rate of speed -inexcossoffiv.ethousandR.P.lLthewobbling action and the saddle'and bobbin be supported toala rge extent by fibre washer 8 for consequently thedegree of friction between the sad e 1 a'ndthe spindle;
